My earlier post was Was moon bombing a success now LCROSS team has successfully found water on permanently shadowed lunar crater . The team was able to observe 25 liters of water with spectroscopic telescope.

The team has also found some components such as Sodium and Carbondioxide which they are analysing.

The impact created by the LCROSS Centaur upper stage rocket created a two-part plume of material from the bottom of the crater. The first part was a high angle plume about 10-12 meters across of vapor and fine dust and the second a lower angle ejecta curtain of heavier material. This material has not seen sunlight in billions of years.

Lunar scientists are trying to find out that how the water has come, whether by comets , meteorites or by some process in moon or the moon surface is creating water.
